The COM3C relay equipped with two push buttons gathers the same characteristics of a two hand control device from III C type. This relay is used to work on presses, the movement of which can be interrupted at any time during the cycle, such as the friction clutch presses, the hydraulic presses, bending machines, etc. 2.Fixing and Wiring 22.5mm wide case mountable on a 35mm symmetrical DIN rail according to DIN 50022. The tightening couple of the terminals is 0.5 Nm. The maximum diameter of the wiring cable is 1.5mm². The wiring between the COM3C and the external elements (pushbuttons, e.g.) has to be performed with wires, whose isolation is dimensioned for a nominal voltage of 250V, even if the signal is only 24VDC. The safety device has to be installed in a cabinet or enclosure, which provide a protection degree of IP54 minimum Technical datas : Power supply: 24V AC/DC; -15%/+10%; 50/60 Hz Current consumption: < 2 W (DC); < 5 VA (AC) Safety outputs: 2 NO; 1 NC 8A/250V AC Auxiliary output: DLC : Electronic current-limiting circuit-breaker Switching power : > 50 mW Reaction time : < 20 ms Temperature operation: -20°C to +60°C Protection class: IP20 MTTFd/DC : 120 years / 99,9% B10d : AC1: 860000, AC15: 300000, DC13: 300000 Housing: Polycarbonate, yellow Connection: Plug-in terminals Dimensions (W x H x D) : 22,5 x 100 x 111 mm Weight : 178 g Standards: EN ISO13849-1, EN574 COM3C : Category III C as per EN574 and category 4 as per EN954-1.
