Honeywell 10102/2/1 Fail Safe Analog Input Module

Description

The Honeywell 10102/2/1 Fail-safe Analog Input Module is designed with four 0-2 V analog input channels. These inputs share a common 0 V connection but are galvanically isolated from both the 24 Vdc and 5 Vdc power supplies. The module can be used either actively, where each input has a separate 26 Vdc, >20 mA short-circuit protected output, or passively, with the supply directly connected to the transmitter. High input impedance allows two 10102/2/1 modules to be connected in parallel, requiring an analog input converter module 10102/A/​.
