Description
The I/O modules are used for signal transfer and signal matching between the plant and the central devices. The input and output circuits are always fed into the I/O modules via cable plugs on the front side. The status of the digital signals is shown on the LEDs of the cable plugs. The power supply is either via the cable plugs or via the I/O bus board. The order of the different I/O module types does not matter.
The current (Ex)i modules exist in 2 construction models:
– non-varnished with PCB covering
– varnished with PCB covering
Any models can be equipped together without free slots between.
Non varnished (Ex)i modules may combined together with non-(Ex)i modules without any restrictions. Also no free slots are necessary on the left or on the right.
With varnished (Ex)i modules with PCB covering the right slot has to remain free in combination with non-(Ex)i modulels or has to be equipped with with a faceplate with partition plate M 2214. This is also valid for slot 16. The slot left to the (Ex)i module may be equipped with any other module. Spare slots are to be covered by faceplates M 2215 (4 units) or M 2217 (8 units).
Usable partition plates and faceplates:
M 2214 Faceplate with partition plate 100*160 mm
M 2215 Faceplate 4 units
M 2217 Face plate 8 units
Cable plugs for intrinsically safe circuits are marked and have coded pins, so that they can only be plugged into the appropriate modules.

All output modules have the following special features:
– To increase the availability the outputs of the safety related output modules can be switched in parallel without additional diodes
– No output voltage occurs when the supply voltage L- should be cut on the output module, so it is not necessary to wire the L- as a ring feeder
– The connection of inductive loads can be done without using diodes at the coil. However it is recommended to connect a diode directly at the inductive load avoiding noise voltages.
– The LED signalling the output status is controlled separately
– The design of the cable plugs enables the two pole connection of the actuators. Together with a two pole supply of the output module an earth fault detection by means of a totalizing current transformer will be simplified
– No time limit for operation in case of a defective output module.
