Purchase now: Phoenix Contact 1291186 Push-in Solenoid Driver
Atlantech Drives provides you the Phoenix Contact 1291186 (Type: MACX MCR-EX-AP-2SD-25-35-LP-SP), the advanced Push-in Technology version of the MACX solenoid driver series. Designed for modern, high-density control cabinets, this device provides intrinsically safe (Ex i) actuation for solenoid valves and LEDs in hazardous zones (0, 1, 2). It offers the same robust SIL 3 safety rating as its screw-terminal counterpart but with a wiring interface that reduces installation time by up to 50%.
Advanced Safety and Efficiency
The 1291186 is a 2-channel, Loop-Powered device. It excels in applications requiring «Functional Safety» according to IEC 61508. The galvanic isolation separates the hazardous area loop from the safe area control system, protecting your PLC from potential faults or surges. The Push-in connection allows for direct insertion of solid wires or ferrules without tools, ensuring a gas-tight, vibration-proof contact that never requires re-tightening.

Maintenance Value: The «Push-in» Advantage
In large chemical plants with thousands of I/O points, maintenance speed is money. The 1291186 allows technicians to disconnect and reconnect wires instantly using the orange release buttons. Expert Tip: The Push-in blocks also feature test points for multimeter probes, allowing you to measure loop current or voltage without disconnecting the wire—a crucial feature for troubleshooting live safety circuits without interrupting the process.
Frequently Asked Questions (FAQs)
Q: Does «Loop-Powered» mean I don’t need a power supply?
A: Correct. The device draws its operating power (approx 0.5W) from the 4-20mA or 24V signal sent by the PLC DO card. No separate 24VDC wiring is needed for the module itself.
Q: Is this module compatible with SIL 3 loops?
A: Yes, it is certified up to SIL 3, making it suitable for the most critical Emergency Shutdown (ESD) systems.
