Part Number: MD-D1022B/12V Features: This item has been assembled, and electrical test passed. Support on board momentary switch, single external momentary switch, double external momentary switches and pulse signal, four control modes. LED indication for relay set and reset action. HF115F 8 Amp DPDT power relay. Power off relay state memory, when the power on again, relay switch will revert to its previous state. The control program based on MCU PIC12F675, this is a flash microcontroller, if you are familiar PIC firmware, you can redesign the program. Panel mount version, size: 72.5 x 47.4 x 18mm (L x W x H) Electrical Parameters: Operating voltage: 9 to 15.6VDC. Operating current: 50mA, at 12VDC. Relay number: G2RL-2 12VDC. Relay switch type: DPDT. Relay switch capacity: 8Amp at 250VAC/30VDC. Pulse mode signal level: High 3~5V, Low 0V. Pulse signal must hold time: High level 1mS minimum, Low level 1000mS minimum. Pulse rising is valid. Terminal block characteristic: Wire range 26-12AWG Mechanical Torque 0.4Nm(3.5Lb-In.) Strip length 7mm Dimensions Pitch 5.0mm(.197") Screws M2.5 Review: Just what I needed. - Fast shipping. Works as advertised. I'm using the DPDT relay contacts to route RS232 to two different sensors depending on the state of the relay. and am using the pulse input to switch relay. The board supply at 12V draws 5 ma when quiescent and about 45 ma when latched, so I use the NC contacts for my primary sensor and NO for the less used sensor.. Screw down unused terminals, Check to see if you have 12v relay before applying Vcc, Cover contacts and switch with blue tape and spray with conformal coating. Cover the Pic chip also if you plan on changing it.
