Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.
Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.
Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.
Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.
Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.
Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.
After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.
Electronics Finder is a website of GID Industrial, an ISO 9001:2015-certified company that has specialized in servicing industrial computer boards and providing other industrial products for sectors including manufacturing, defense, aerospace, entertainment, healthcare, and more by utilizing our combined skills and vast international network of trusted suppliers since our founding in 2015.

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.)
