I/O modules Parts of the H-S81-HS System
2.4.3 S81-F4002-1 & S81-F4002-2
Description
Safety related module with 2 x 4-20mA analog inputs and two thresholds to be
programmed on the module through the operator cycle. The following transducer
types can be connected to this module: Explosion Sensors, Air Quality Sensors,
Oxygen Sensors, Temperature Sensors, 4-20mA General Sensors. The channel is
continuously tested during operation. The module features 4-20mA outputs that
provide the current value measured on the input. The analog value of each chan-
nel can be transferred to a DCS by means of the S81-F7006-1 Modbus RTU
module. This module can be duplicated for fault tolerant systems; in this case,
the two modules shall be placed on two adjacent racks in the same position. In
this configuration, the two detection lines are connected to both modules.
Technical Features
Status Indications
Module front panel includes three LEDs and a three-digit display for each channel.
