Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The Phoenix Contact REL-OR3/LDP-24DC/3X21 is a plug-in octal power relay with three changeover contacts, combining generous contact spacing with the serviceability of an 11-pin octal base. Order number 2903693 identifies the complete relay: a 24 V DC input coil with integrated freewheeling diode, a test button for manual actuation during commissioning, and both an LED status indicator and a mechanical switching position indicator that shows the true contact state even with the coil de-energized. The relay belongs to Phoenix Contact's Rifline REL-OR family of plug-in relays with power contacts, where each of the three single contacts is rated 10 A at a maximum switching voltage of AC 250 V — three independent poles for switching three phases, three separate circuits, or mixed voltage systems from a single coil signal. Observe polarity when wiring: terminal A1 must be positive and A2 negative because of the freewheeling diode. The coil draws approximately 80 mW with a resistance of about 430 Ω, operates in roughly 18 ms and releases just as quickly, making the relay equally comfortable in timing-critical interlocks and general-purpose switching duty. The large contact gaps and clear mechanical flag are exactly why panel builders specify this family for machine safety circuits, heater banks, solenoid groups and motor auxiliary duties across Pakistani industry. The relay plugs into any standard octal socket, so replacing a fatigued unit takes seconds without disturbing a single field wire — a decisive advantage inside crowded sugar mill and cement plant panels where downtime windows are measured in minutes. The module measures approximately 35 × 35 × 54.5 mm, ships from Poland under EAN 4046356759069, and carries the test button and dual indicators as standard equipment rather than costly extras. Al Imran Enterprises supplies genuine Phoenix Contact relays together with their matching octal sockets to maintenance teams across Lahore and wider Pakistan, verifying order numbers against official datasheets before every dispatch.
