Serial Port Control 20-Channel Relay Output Controller

1. Product synopsis

JMDM-COM20MR is a high reliable stability of industrial single-chip digital serial controller, relay controller, Onboard 20 10A large - capacity relay which independent research and development by Shenzhen jingmin digital machine Co., Ltd. It is focused on the 20-channnal 10A of large load control, such as lightning, heating wire, power switch, and the other high-power devices, and collect 4-channel I/O input signal contemporary; Can be connected photoelectric, capacitive, inductive, Hall-style and a variety of sensors and input switch, convenient to plenty of industrial and civil application occasion of stroke switch, infrared switch of the signal detection and condition input to control the output action.
The products have following characters:

1). Product design and quality: Professional industrial-grade high reliable of lighting prevention and anti-strong electromagnetic interference circuit design, the circuit layout compact and reasonable, with excellent heat dissipation, majority use of patch type chips and electronic components, the product procedure with high security, with reliable industrial quality and stable performance, competence to all kinds of large electromagnetic interference and harsh environment industrial sites, such as arc current, welding current, inverter, and the other workplace can be stable used.

2). I/O: 4-channel full Opto-isolated input and 20-channel relay output; Output with super load capacity;

(1) Each of the 20-channel relay are fetch out a normal open point and normal close point, it can control 20 groups of different voltage switch;

(2) Each channel relay output the maximum load is 220V 10A, output use special high filter circuit to prevent electric shock ignition, Increase the life of relay.

(3) Two kinds of communication interface is optional: An RS485 interface and an RS232 interface optional;

(4) Three kinds of working methods: Support for independent control, RS232 serial port monitor, RS485 serial monitoring.

(5) Four toggle switches: Direct hardware addressing to facilitate multiple network use;

(6) The precise time control: With the system clock enables precise time control;

(7) System stability: With industrial-grade anti-lightning, anti-strong electromagnetic interference, high reliability, no crashes.

(8) Relay working status indicator: Each relay output has a indicator light that easy to observe the working status.

(9) Industrial shell, dustproof, easy for installation: Rail or screw mounts;

(10) Simple serial communication protocol, the convenience of customers for the secondary development
