PM400 Power Supply Specifications
Print Friendly, PDF & Email

The PM400 Power Supply is a device that supplies 12 VDC power to the InfraStake modules. Each PM400 provides lamp power for up to (4) InfraStake modules.

What’s Included?

Each PM400 comes with the following:

  • Two 24 VDC connectors
  • Two AS-I connectors (only needed for AS-I communication method)
  • Ribbon cable (only needed for Discrete I/O communication method)
  • Module power connector
  • 9-conductor module power cable

Controller Connections

Connections to a PLC or other controller are typically made through the Discrete I/O Interface (J303) connector located on the InfraView Interface Board. The connection can also be made through the AS-Interface (J304 or J305) connector.

Discrete I/O Interface – J303

The PM400 has a 10-conductor ribbon cable used to control 1 to 4 modules.

  • Ribbon cable length must be 3 meters or less to comply with CE.
  • Lamp control outputs must be solid-state.
  • Each lamp must be kept at full power (no pulsing) for the first 0.5 seconds after turn-on.

AS-Interface – J304 & J305

The AS-I network requires an AS-I master and AS-I power supply which are offered by most PLC manufacturers. The use of AS-I is typically only cost effective on systems with 13 or more Infra lamps. Extol prefers the Wago System 750 AS-I master (P/N: 750-655) and AS-I power supply (P/N: 787-692) because they are cost effective and when combined with a Wago bus coupler, can be controlled over any I/O network. Go to or for more information.

AS-I Connections

Both J304 and J305 have the same pinout.
