DTB25

25MPCB

The DTB25 allows easy terminal block access to all pins of the DB25 connector. The 25MPCB allows easy solder pad access to all pins of the DB25 connector.

3 & 4 Channel Relay Modules

Control up to sixteen devices using your PC

Multi-channel relay boards are SPDT for 24 VDC or 120 VAC at 10 A max. Four-channel Model SDDRB4 works with SDD16 series modules. Power required is 11 to 16 VDC @ 200 mA per board. Three-channel Model SDARB3 works with 232SDA12 and 485SDA12 modules. Power required is 11 to 16 VDC @ 110 mA per board.

SDDRB4

• SPDT for up to 24 VDC or 120 VAC @ 10 A
• DB25 M connectors plug into SDD16 & SDA12 modules
• Terminal blocks for relay connections
• Cascade multiple modules to control up to 16 devices
• Panel mount or DIN rail mount (with SNAPTRACK)
