Schmersal Protect-PE-02 Safety Component

PROTECT-PE-02 (Item number 101210948) is a Schmersal safety controller that acts as an input expander for safety circuits, allowing up to four sensors per interface to be connected with non-isolated signals. It provides individual signaling outputs for each connected sensor and a group signal, and includes two safety contacts for monitoring safety devices such as magnetic safety switches, emergency-stop devices, interlocks, and more. The unit complies with EN IEC 62061, EN ISO 13849-1, EN IEC 60947-5-1, EN IEC 60947-5-3, EN IEC 60947-5-5, EN IEC 61508, EN IEC 60204-1, and EN IEC 60947-1, and features six LEDs, two normally closed contacts, seven signaling outputs, automatic reset, wire-breakage detection, earth connection detection, and integral diagnostics. It operates on 24 V DC control voltage (input HIGH 19–28.8 V DC), consumes about 1.7 W, and offers PFH 2.00 × 10⁻⁷/h with a 20-year mission time and DC 60% diagnostic coverage, suitable for SIL 2 applications and Stop Category 0. The housing is glass-fibre reinforced thermoplastic, ventilated, and the unit weighs about 180 g, making it a compact option for machinery safety systems including guard monitoring, pull-wire emergency stops, and safety interlocks.
