Honeywell 10102/2/1 Fail Safe Analog Input Module

The Honeywell 10102/2/1 Fail-safe Analog Input Module offers four 0-2 V analog input channels, with galvanic isolation from the 24 Vdc and 5 Vdc power supplies. It operates in two modes: active mode with independent 26 Vdc power and short-circuit protection for each input, and passive mode, where power is supplied directly from the transmitter. The module’s high input impedance allows for parallel operation of two modules, requiring an additional analog input converter module (10102/A/​). This design makes the module suitable for industrial and process control applications that require high reliability and flexibility.
