Honeywell 51304584-200 TDC 3000 In Stock New

The EPDGP I/O is the newer I/O card for the EPDG and EPDG2 peripheral interface on a Honeywell Universal Station.

This I/O board has connectors for the station's video, cursor control, keyboard, Zip or Bernoulli drive, and printer.

Rev G or above must be used on stations with a Bernoulli or Zip drive.

51304584-200 Introduction

The Honeywell TDC 3000 Basic Controller consists of a microprocessor-based card file (model CB 120) providing multifunctiona!

process control, and a dedicated terminal panel for process signal interconnection.

The controller is configured by the user to provide precision automatic control for 8 independent or cascaded control loops.

A reserve controller capability is available in the Basic Controller Model CB121.

Controller Types

Two Basic Controller types are available, the CB120 and the CB121.

These controllers are identical with one exception in the system security area.

CB 120contains a core memory printed wire board that retains restart infomation for a stalled or powered downcontroller file.

Configuration and operating data for each of the eight slots is stored in the controller's non-volatile core memory.

It is constantly updated during normal operation, and its integrity is maintained during a system failure

or power loss.

This data along with a resident restart program is used to restore each of the 8 loops 10 a restart condition as determined at configuration.

The controller is restarted by the operator who enters a restart command from the operator interface.

CB121 contains a Complementary Metal Oxide Semiconductor (CMOS) memory in place of the core memory as used in the CB120 model.

This CMOS memory is a component of the failsafe

Uninterrupted Automatic Control

System (UAC).

This system facilitates

the automatic substitution of a reserve

Controller Interface

The interface between the process and the Controller, exists at the printed wire terminal panel (C-TCB20, C-TCB21, or C-TCB30).

Input wires from field sensors and output wires to final control elements are connected at terminal strips as indicated in Figure 3 and 4.

Terminals 10 and 11 on C-TCB20 and C-TCB21 also may be used for low and high alarm wiring, while terminals 12 and 13 provide outputs for left and right indicator lamps (LIL and RIL) on Analog Displays.

Terminal panel C-TCB30 does not provide for alarm or indicator lamp outputs. However, it can accommodate alarm functions if used in conjunction with terminal panel TPM01 or TPM02.

On TCB20 or TCB21. each one of the eight terminal strips is devoted to only one of the eight slots of a BASIC Controller.

On TCB30, each one of four terminal strips accommodates two of the eight siots.

When TPM01 or TPM02 is used, each one of four terminal strips provides for up to four siots, therefore

each TPM01 or TPM02 can accommodate two Basic Controllers.

The signais at the terminal strips are connantorl internally.
