BEA LO21 Safety Module

The BEA LO21 is a lock-out relay module for swing doors that use BEA BODYGUARD overhead presence sensors. It reads door open and closed positions from the operator motor voltage and sends that to the BODYGUARD over data lines. Power is 12 to 24 VAC or 15 to 24 VDC. An optional safety beam input cancels the inhibit signal during closing. If the beam is blocked while the door closes, a safety signal goes to the door control safety input. Outputs are two SPST relays rated 60 VDC / 120 VAC, 2 A DC / 0.5 A AC. Current draw is 10 mA at rest and 50 mA max. Before You Order Listed here as the replacement for the BEA MC15 safety module. BEA's guide shows it with BODYGUARD and DK-12 safety sensors and dry contact safety beams. For BEA PARALLAX packages, BEA offers the LO21P version. Power: 12 to 24 VAC or 15 to 24 VDC.
