Safety monitoring relays SR103AM Sr103Am Dual-channel Safety monitoring relay • Power requirements—the SR103AM will accept 24 VAC/DC or 115 VAC • Inputs—the SR103AM will accept single or dual N/C inputs or dual inputs from a light curtain (see SR102AM for application wiring for a light curtain) • Outputs—the SR103AM has 3 N/O outputs to route power to the coils of power contactors, plus 1 N/C auxiliary output for signaling purposes • External Device Monitoring (EDM) is provided with a N/C loop between S11/S12 and S21 on the SR103AM • Monitored manual or automatic/manual reset modes are available on the SR103AM. Monitored manual reset requires closure of the reset circuit followed by opening of the circuit. Reset occurs when circuit is opened. Auto reset requires only closure of the reset circuit as reset occurs when circuit is closed. r C US Conforms to EN60204-1, EN954-1, VDE 0113-1 UL and C-UL listed Specifications TÜV Rheinland approved electrical All models Sr103Am01 Sr103Am02 Power Supply: ±10%, 50-60 Hz 24 VAC/DC 115 VAC Power Consumption: Approx. 1 VA i Safety Inputs: 1 N/C or 2 N/C or 2 solid state (light curtain) Max Input Resistance: 800 Ohms per channel Outputs: 3 N/O + 1 N/C auxiliary Output Rating AC: Inductive AC-15, 3 A/230 VAC Output Rating DC: Inductive DC-13, 2 A/24 V Min Switched Current/Voltage: 10 mA/10 V Impulse Withstand Voltage: 2500 V Max Drop-Out Time: 12 ms (75 ms by removing supply voltage) Max Output Fuse: 6 A quick-acting or 4 A slow-acting Reset Mode: Monitored manual (S11-S21) or automatic/manual (S12-S21) Contactor Monitoring: N/C loop S11/S12-S21 mechanical Mounting: 35 mm (1.38 in.)
