| Datasheet | Download Datasheet |
The IDEC EB3C-R10DN is a 10-channel relay barrier from IDEC's EB3C series: it reads contacts in a hazardous area (Zone 0 or Class I Division 1) through intrinsically safe circuits and repeats them as relay outputs (1NO per channel) in the safe area.
Supply 24V DC (+/-10%). Inputs: 12V DC 10 mA, separate or common wiring. Outputs: Resistive 250V AC 3A, 24V DC 3A; inductive 250V AC 3A, 24V DC 2A; common terminal 8A; minimum load 0.1V DC 0.1 mA. Response: 12 ms on, 10 ms off maximum. It mounts on a 35 mm DIN rail or a panel, with M3 screw terminals, and measures 171.5 x 75 x 77.5 mm (W x H x D).
It is associated apparatus [Ex ia] IIC: FM and UL Class I, II, III Division 1, Groups A-G, and Class I Zone 0 AEx [ia] IIC; ATEX and IECEx [Ex ia] IIC / IIIC. Entity parameters: 1-channel separate wiring: Uo 13.2 V, Io 14.2 mA, Po 46.9 mW, Co 470 nF, Lo 87.5 mH; 16-channel common wiring: Uo 13.2 V, Io 227.2 mA, Po 750 mW, Co 490 nF, Lo 0.6 mH. It operates from -20 to +60 °C. Approvals: FM 3047250, UL E234997, PTB 09 ATEX 2046, IECEx PTB 10.0015, CQST CNEx14.0047, KCS, TIIS.
