Contactor and Relay (Not in the Acti 9 Range)
Overview
A contactor or relay powered with 24 Vdc allows control and indication of impulse relay or contactor from the I/O Smart Link by 24 Vdc signals (Y3). This should have the following characteristics:
-
The relay or contactor coil must not draw more than 100 mA
-
The indication contact must be low level type
The Modbus information in the following table is given for a contactor connected to channel 1.

(1) To address the channel N (1≤ N ≤ 11) registers, add 40 × (N – 1) to the channel 1 registers. (2) The I/O Smart Link device resets the bit to state 0 when the order is taken into account (unless no product is connected to the channel). If bits 0 and 1 of address 14202 are activated simultaneously, the I/O Smart Link device does nothing. |
