The Chameleon Discrete Automation Module (DAM-1) offers high-performance logic and batch control. The DAM-1 module contains ten digital inputs, eight digital relay outputs, four user-programmable push-buttons, and eight user-addressable tri-color digital readouts that are configured in software. It is powered by an ARM processor with sufficient computational power to handle the most demanding applications. The DAM-1 embedded firmware is stored in its flash memory and is upgradeable: you can rest assured that the hardware investment you make in Chameleon will not become obsolete.
Its ten universal digital inputs are capable of accepting a broad range of AC and DC signals with no reconfiguration or rewiring required. Its eight digital outputs are Form C mechanical relays.
The DAM-1 module is available in two wiring configurations for the digital outputs: isolated and banked. In the isolated wiring hub configuration, every relay output has a unique common, normally open, and normally closed terminal connection point. The banked wiring hub configuration provides two power termination groups and arranges the digital outputs into two banks of four relays—the relays in each bank have their common terminal tied together (but each relay maintains unique terminal points for the NO and NC contacts). While the isolated wiring hub configuration provides the most power sourcing flexibility, the banked wiring hub is advantageous in applications that have common power sources by eliminating the need to splice wires. When ordering, use DAM-1ISO for the isolated wiring hub configuration and DAM-1BK for the banked wiring hub configuration.
Each DAM-1 module provides convenient tag holders that can be associated with its digital readouts and push buttons. Multiple modules can be attached to each other to expand I/O capacity and to provide redundant I/O connections. They can also be combined with other Chameleon modules to form a full-featured programmable automation controller. As with all Chameleon modules, DAM-1 units are hot-swappable.
