ALC Automated Logic Corporation Z540V Z-Line Zone Control Module [New] in Tempe, AZ, USA

. . . . . There are three Z-Line modules. They are the Z-Line Rev 8, the Z-Line Rev 4 (Exec. 4) and the Z-Line Rev 4 (Exec. 3.6). This document details Z-Line Rev 8. All three Z-Line modules look very similar. Therefore you should familiarize yourself with the physical differences in the Z-Line modules. The drawing in this document depicts the Rev 8 Z-Line module. As indicated by the Z-Line drawing in this document, the Rev 8 module contains a cutout through which the EEPROM is visible (the Rev 4 does not). Additionally, the Digital Output's LEDs are located on the board. On the Rev 4 modules, the LEDs are raised and displayed through the metal. All Z-Lines are part of the I/O Hardware family of control modules designed specifically for zone control. A single board provides the power circuitry, the microprocessor, and nonvolatile memory. The module's name indicates the number of outputs (first digit) and inputs (second digit) which it provides.
