HIMA HIMatrix Safety-Related Controller DI 32 01

Product Description

The DI 32 01 is a module with 32 digital inputs and is used for the modular F60 system. The

inputs are galvanically separated to the I/O bus.

The module can be inserted in the F60 subrack's slot 3...8. Slots 1 and 2 are reserved for the

power supply module and central module, respectively.

The module has been certified by the TÜV for safety-related applications up to SIL 3

(IEC 61508. IEC 61511 and IEC 62061), Cat. 4 and PL e (EN ISO 13849-1) and SIL 4

(EN 50126. EN 50128 and EN 129).

Further safety standards, application standards and test standards are specified in the

certificates available on the HIMA website.

Safety Function

Safety-Related Inputs

The module is equipped with safety-related inputs.The module is equipped with safety-related

inputs. These inputs are divided in 4 groups of 7 inputs and 1 group of 4 inputs (I29...I32). Refer

to Table 10 for more information about terminal assignment. Each group is equipped with a

common short-circuit-proof supply LS+.

Reaction in the Event of a Fault

If the module detects a fault on a digital input, the user program processes a low level in

accordance with the de-energized to trip principle.

The module activates the ERR LED.

In addition to the channel signal value, the user program must also consider the corresponding

error code.

The error code allows the user to configure additional fault reactions in the user program.

Line Control

Line control is used to detect short-circuits or open-circuits, e.g., on EMERGENCY STOP inputs

complying with Cat. 4 and PL e in accordance with EN ISO 13849-1. Line control can be

configured for the F60 system.

The digital outputs are pulsed. This allows monitoring of the wires to the digital inputs of the

F60 DI 32 01 or F60 DIO 24/16 01 module.

A fault reaction is triggered if one of the following faults occurs:

 Cross-circuit between two parallel wires.

 Improper connections of two lines (e.g., TO 2 to DI 3).

 Earth fault of a line (with earthed ground only).

 Open-circuit or open contacts, i.e., including when one of the two EMERGENCY STOP

switches mentioned above has been engaged.

The fault reaction includes the following actions:

 The ERROR LED on the controller's front plate blinks.

 The inputs are set to 0.

 An evaluable error code is created.
