Description

Safety related module with 1 x 4-20mA analog input and two programmable
thresholds. It can control the following transducer types: explosion sensors, air
quality sensors, oxygen sensors, temperature sensors, 4-20mA general sensors.
The channel is continuously tested during operation. The module features a 4-
20mA output that provides the current value measured on the input. This analog
value can be transferred to a DCS by means of the S81-F7006-1 Modbus RTU
module. This module can be duplicated in fault tolerant systems; in this case, the
two modules shall be placed on two adjacent racks in the same position. In this
configuration, the detection lines is connected to both modules.
