Product Overview

McCain’s 170 Controllers are industry standard controllers in full compliance with Caltrans Transportation Electrical Equipment Specification (TEES) standards. The 170 controllers are primarily designed to operate eight-phase dual ring intersections. Built to McCain’s high quality standards, the controllers’ rugged and dependable construction is reliable and capable of operating in harsh environments. The controllers’ 19-inch Electronics Industry Alliance (EIA) rack mount form allows them to easily fit any standard EIA-based cabinet. Built on a modular design, McCain’s 170 line of controllers accommodate the easy interchange of modules and components.

Benefits

  • Multi-purpose microcomputer
  • Operates in harsh environments
  • Vertical board design
  • Accepts two plug-in communications modules
  • Low maintenance
  • Low wattage, removable power supply

Standard Features

CPU Module:
The CPU module includes the MPU; a clock generator capable of doubling the basic frequency; ACIAs with RS232 interface and five clock speeds; 32K of battery backed, write protected RAM; decode logic; and dual bus drivers.
Input Module:
The single input module uses CMOS technology to increase noise immunity in hostile environments. A total of 44 inputs are directed to the C1 connector. Includes Down Time Accumulator (DTA), power-up/power-down circuitry, and 2.2 farad standby power capacitor.
Output Module:
A single output module contains all output circuitry. Output drivers operate switch packs in the cabinet and LED indicators on the front panel. 56 of the outputs are directed to the C1 connector and 16 are used to operate the front panel. Lightning protection devices are used to eliminate high energy voltage and current spikes.
Power Supply:
The power supply module is an efficient and easily removable AC/DC linear power supply. A long holdup after power-down feature, assures that all supplies are held within specifications following a power failure (70 milliseconds for the 170E/170E HC11 and 550 milliseconds for the 170 ATC HC11). The power supply is self-contained and input power is supplied through an 18-pin power connector to the mother board.
Chassis:
Components are manufactured on computer numerical control (CNC) equipment for best form and fit. Module interconnect is provided by a mother board with separate busses for I/O and memory. Modules are vertically oriented with mechanically keyed PC edge connectors.
