DC60MP datasheet

Description

The DC60MP is a DC-controlled solid-state relay (SSR) capable of switching up to 60VDC at 3A, designed in a compact epoxy-encapsulated package for PCB mounting. It features high optical isolation, robust surge handling, and integrated heat-spreader technology for improved thermal performance and long-term reliability. This relay is widely used in industrial control, automation systems, and high-density PCB relay applications.

Features

  • Switching capability up to 60VDC and 3A load current
  • 4,000V optical isolation between input and output
  • Rugged epoxy encapsulated construction
  • High surge tolerance with pre- and post-test validation
  • Integrated heat-spreader for efficient thermal dissipation
  • Designed for high-density PCB mounting

Absolute Maximum Ratings (Tc = 25 °C)

Parameter Symbol Value Unit
Load Voltage VLOAD 60 VDC
Load Current ILOAD 3 A
Isolation Voltage VISO 4000 Vrms
Operating Temperature Top -40 to 85 °C
Storage Temperature Tstg -40 to 100 °C

Design Notes

  • Ensure adequate PCB copper area for heat dissipation despite built-in heat spreader
  • Use proper input current limiting resistor for LED drive inside SSR
  • Consider leakage current in off-state for sensitive loads
  • Snubber circuits may be required for inductive loads
  • Verify thermal derating at elevated ambient temperatures

Typical Circuit Usage

  • DC load switching in industrial control systems
  • PLC output modules
  • Motor and solenoid control circuits
  • Battery-powered switching applications

Description

They are used in gas leakagedetecting equipments in family and industry, are suitable for detecting of LPG, i-butane, propane, methane,alcohol, Hydrogen, smoke.

Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
