Point Expansion Modules
Figure 1. Point Expansion Modules.
Description
The Point Expansion Modules provide cost–effective
methods for controlling and monitoring remote points.
As an extension of the field panel, this capability
expands the point capacity of the APOGEE®
Automation System and provides for efficient
placement of the point terminations close to the
sensors and loads.
Features
• Compatible with the MEC Point Expansion Bus
and any field panel Floor Level Network (FLN)
• Analog or digital points, which provide for point
expansion capability to match the application
requirements
• The terminal blocks are removable for easy
termination and servicing of field wiring
• Optional Hand-Off-Auto (HOA) switches

Figure 2. Digital Point Expansion Module (DPX).
Analog Point eXpansion module (APX):
Available in 8AI and 4AI/4AO models. Analog inputs
are user selectable to be 0-10V, 4-20mA, or 1K RTD.
Analog outputs are selectable to be 0-10V or 4-20mA.
Digital Point eXpansion module (DPX):
Available in 8DI/4DO and 4DI/4DO models. The digital
inputs are dry contact with four of the inputs being
pulse accumulator points. LEDs on the Digital Point
Expansion modules indicate On/Off status for DI and
DO points. The relayed digital output points support
110/220V Form C relays.
