3.6 DIGITAL CONNECTIONS

Open Circuit Detection:

The following modules require that a 20 to 30 kOhm resistor be mounted in parallel of each

input captor to get open circuit detection for that channel. With an inductive captor, the

minimal current is 1 mA.

• ICSI 08 D1 - 8 Non-Isolated 24Vdc Inputs

• ICSI 16 D1: 16 Non-Isolated 24Vdc Inputs

• ICSC 08 L1: 8 Configurable 24Vdc Inputs or 24Vdc 500mA Transistor Outputs

• ICSK 20 F1: 12 Non-Isolated 24Vdc Inputs & 8 Isolated Relay Outputs

Initialization:

After being configured and wired:

– the unit initializes itself after power On.

– the error led goes out after initialization.

– the input/output status is displayed on the led's.

Fault Indication:

The led’s on the front face of each unit indicates the type of error. If an error occurs, the red

led is ON. See Section 4, Diagnostics for failure testing.
