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

InfraView Card Connections
| Connector | Name | Description |
|---|---|---|
| J101 | Lamp Connections | Supplies power to InfraStake modules |
| J102 | Lamp Power | Receives power from 12 V power supply for modules |
| J301 | Control Power | Receives power from machine |

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.

| 9 | Lamp 3 Status Output | 22-28 AWG Stranded | Red |
| 10 | Lamp 4 Status Output | 22-28 AWG Stranded | Brown |
- 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 as-interface.net or wago.com for more information.
AS-I Connections
Both J304 and J305 have the same pinout.
| Pin | Description | Wire Specifications |
|---|---|---|
| + | AS-I + (30.5 VDC & Data) | 18-22 AWG Stranded |
| - | AS-I - (30.5 VDC & Data) | 18-22 AWG Stranded |
AS-I Power Requirements
The power supply must be AS-I compliant.
| Description | Specification |
|---|---|
| Voltage | 30.5 VDC |
| Current | 6 mA |
