1734-IE4S Safety Analog Input Module Features
• 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 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.
