DEVICE DESCRIPTIONS

5.1.11 8 I/O Control Module (NRS 90219)

This control module provides 8 floating control inputs and 7 floating logic level outputs (0 V, 24 V). An additional output provides pole change impulses for controlling slave system clocks. Contact is established via 4 x RJ-45 sockets providing 8 contacts each. The module can be installed in slot 5.

The slave clock output (NU, OUT 1) is short-circuit proof; up to approximately 40 slave clocks can be connected. Please make sure to connect all slave clocks according to their correct polarity.

The control outputs (OUT 2 - 8) are capable of switching voltages of either polarity and up to a maximum current of 1 A.

The control inputs (IN 1 - 8) are capable of handling voltages of either polarity between -31 V and +31 V; for voltages between 0 and 5 V the inputs are not active (low), for voltages between 10 V and 31 V the inputs are active (high). The control inputs can ignite switching functions or macros either during a change of state or in any stationary state. This offers the possibility to monitor line idling currents (e. g. in fire alert system installations).

Note: The opto-coupler inputs are primarily meant to prevent noise loops that can result from dropping voltages in long distance cabling. They are not suitable for separating networks from each other. Therefore, only floating sources should be connected.
