S5-95F Expansion of Basic System with External I/Os
Example: Indirect Control of Actuators via Coupling Relays with P-M Control (Type L)
Insert one module into slot n of subunit A and the other module into slot n+1 of subunit B, with
n being an even number between 0 and 30 (see section 6.2).
Set the selector switch of the module in subunit A to P (P output) and the selector switch of the
module in subunit B to M (M output) or vice versa.
Connect the 24 V DC supply voltage to terminals 1 and 2.
Wire the outputs with the coupling relays (as shown in Figure 5-15).
Wire the actuators.
Parameterize the outputs in DB1.
Figure 5-15. Example for Indirect Control of Actuators (one P output and one M output)
