POINT GUARD I/O SAFETY MODULE 4 SAFETY ANALOG INPUT MODULE

• Connection of up to four voltage or current sensors. • Sensor power outputs are individually current-limited and monitored. • Measurement of process variables, such as temperature, pressure, or flow rate. • Seven configurable input ranges (±10V, ±5V, 0…5V, 0…10V, 4…20 mA, 0…20 mA, Tachometer). • Tachometer mode converts 24V DC switching signals into pulses per second. • Single-channel or dual-channel for SIL 3-rated safety devices and applications. • Dual-channel mode evaluates the consistency between two input signals (channels), which allows use of the module in applications that are rated up to and including SIL CL3/PLe/Cat. 4. • You can configure a discrepancy time to control how long two channels are allowed to be discrepant before a fault is declared.
