Safety function of CS DM series modules for two-hand control

The safety function of CS DM modules guarantees safe two-hand control, preventing activation of the machine if the buttons are not pressed simultaneously. The module verifies synchronisation, checks circuit integrity, carries out self-monitoring, and immediately brings the system into a safe state in the event of release or failure.

Applications of the CS DM series

Presses and metal forming systems

Machine tools with crushing risk

Automatic production lines requiring synchronised activation

Safety architectures that require two-hand control, up to Type III C

Safety levels and start up modes

High level of safety

International standards

Two-handed function up to Type III C in accordance with EN ISO 13851, up to Category 4 in accordance with EN ISO 13849-1 and SIL 3 in accordance with EN IEC 62061.

Start-up modes

Two-hand-control functionality

Both buttons must be pressed within the maximum synchronization time. Releasing either button immediately triggers deactivation of the output.

2–3 outputs

Output configurations

Output configurations vary from 2 to 3 safety contacts.
