Product Description:

The KSM 131 safety module is produced by Kollmorgen as part of the KSM Safety Solution Modules series. It serves as a configurable safety controller that supervises sensors and drives, evaluates preprogrammed logic, and issues safe shutdown commands when a hazardous condition arises. In automated cells, it connects directly to light curtains, emergency-stop buttons, and encoder-based feedback, consolidating the safety layer that would otherwise require multiple relay blocks. This arrangement supports centralized monitoring of protective devices and helps the machine react quickly when guarded access is opened or motion limits are exceeded.

Physically, the module measures 45 mm wide, 115 mm deep, and 100 mm high, which helps reduce DIN-rail use in compact cabinets. At a mass of 300 g, it mounts without extra support, and its peak draw of 3.8 W keeps heat generation low during continuous operation. Screw terminals accept conductors up to 1.5 mm², while twelve safe digital inputs, ten safe digital I/O lines, and eight OSSD-compatible inputs connect guarding devices. Two pulse output channels and two standard outputs send status signals to drives or a PLC, so the module can coordinate stop requests, reset states, and safety feedback through one control point.

From the safety side, the device has a protection class of IP52, permitting use in dusty environments where dripping water may be present. It is certified to performance level PL e and safety integrity level SIL 3, supporting applications that require a very high degree of fault tolerance in the stop chain. Its mean probability of dangerous failure per hour is capped at 1.1 × 10^-9, and the internal diagnostic structure continuously monitors the ten safe output paths, dual microprocessors, and redundant pulse outputs. These functions allow the module to supervise emergency stops, gate switches, and motion-related safety signals without relying on external relay logic for every protected zone.
