A cost effective solution for pressure applications requiring monitoring and process control of non-corrosive, non-ionic working fluids such as air, dry gases and similar. The pressure sensor is available in absolute and differential models and pressure ranges from 0 to 100 psi. Two independent digital inputs and a 24 V excitation voltage provide additional transducer and/or logic interfaces for measuring such variables as flow rate of the fluid being monitored.

### Detailed Description

The Tiger 320 Series controller has four input channels capable of processing almost any input signal type.The direct pressure sensor input module IGYX uses only channels 1 and 2 and also the controller s digital inputs D1 and D2.

The input module processes the pressure input via a b uilt-in pressure sensor capab le of processing an absolute or diff erential pressure input. The pressure signal is then f ed to CH1 f or further processing. Gain setting resistors are f actory installed to optimiz e the full scale output for each pressure r ange. Contact Texmate when ordering to discuss your pressure range requirements.

In addition to the pressure sensor, there is a digital interf ace with independent dual inputs and a 24 V excitation voltage. Each input uses an input header to interface to standard open collector (PNP or NPN), TTL, or millivolt digital signals. Frequency or counter inputs are f ed through input 1 where the y are conditioned and have the option of lo w-pass filtering, via a selection header, then fed to CH2 for further processing. Input 1 can also receive status inputs that are conditioned and fed to the controllers digital input D1, where it can be used f or setpoint control or macro functions. Input 2 receives status inputs that are conditioned and fed to the controllers digital input D2, where it can also be used f or setpoint control or macro functions.

Tiger 320 Series Meter Settings Channel 1 (CH1) and channel 2 (CH2) configur ation settings for the IGYX input module are selected in Codes 2 and 4 of the Tiger

320 Series meters main programming mode. CH1 single or dual pressure input settings are configured in Code 2 and must be selected as a voltage input. CH2 frequency and counter settings are configured in Code 4.

Status inputs D1 and D2 are an activation source for any of the six available setpoints. The selected setpoint is individually configured in the setpoint control function settings menu of the setpoint programming mode. Enter the setpoint programming mode, adjust the activation value of the selected setpoint, and then enter the rele vant setpoint control function menu (SPC_X) and select the requir ed status input (D1 or D2).

### Interface Configuration

### Examples

The following example diagrams show the various header settings required f or a range of digital inputs to the digital interf ace (inputs

1 and 2). Inputs to the pressure sensor are not sho wn, but can be either absolute or diff erential.

Example 1 Frequency Input with 1 kHz Lo w-pass Filter Figure 3 shows a transducer with an open collector NPN transistor output connected to digital input 1 (CH2/D1). In this case the transducer has its o wn power supply and the signal output is an open collector NPN transistor. By positioning input header CNT1 to the NPN position, a 10 k pull-up resistor ties the signal output to +24 V. The negative supply of the transducer is common to the g round

(GND) pin of the input module. When the transistor switches ON, the voltage of digital input 1 changes from +24 V to 2.5 V (J2 closed).

Example 2 Monitoring Voltage Level Shifts Figure 4 shows a transducer with an open collector PNP transistor output type connected to digital input 2 (D2) to monitor voltage level shifts. In this example the transducer uses the +24 V supply of the Tiger meter. By positioning input header CNT2 to the PNP position, a

10 k pull-down resistor ties the transducer signal to 2.5 V (J2 closed). When the transducer switches ON, the signal output changes from 2.5 V to +24 V DC. The Tiger 320 Series controller software reads digital input D2.

Example 3 TTL Output Configured as a HS Do wn Counter Figure 5 shows a transducer having its own external power supply of +5 V DC connected to digital input 1 and configured as a hi gh speed down counter on CH2. Input header CNT1 is positioned for TTL and this forces the 0 to 5 V transducer signal to be pulled down to 2.5 V (J2 closed). This ensures the input signal v aries about 0 V and all counts are detected.

Figure 5 TTL Signal Connected to Digital Input 1

Example 4 Transducer Input Configured as Up Counter Figure 6 shows a transducer that produces a slow 300 mV peak-to-peak output. The magnitude of the signal is less than 2.5 V peakto-peak. This means jumper J2 must be cut so that the mean signal passes through z ero. The signal is connected to input 1 as an u p counter with low-pass filtering.

Figure 6 mV AC Signal Connected to Digital Input 1

Example 5 Switch Closure Figure 7 shows a switch connected to both digital inputs. Digital input 1 acts as an up counter with low-pass filtering to record the number of switch closures. Digital input 2 acts as a status input on D2. Input 1 header (CNT1) and input 2 header (CNT2) are set to NPN for 10 k pull-up resistors to +24 V. Closing the switch sets both inputs to 2.5 V.
