Installation 2704 Controller 2.3.6. Digital I/O Eight digital I/O connections are provided as standard. They can be configured as: 1. Inputs Run, Hold, Reset, Auto/Manual, etc, - logic or contact closure. 2. Outputs Configurable as Control outputs, Programmer Events, Alarms, etc. Digital IO is not isolated from instrument ground. Digital Inputs (Logic Inputs or Contact Closure in any combination) Common Logic inputs (1) Contact closure inputs DC D1 D2 D3 D4 D5 D6 D7 D8 Common This terminal can be used for Digital Input only (not DO) Note 1: Logic inputs can accept drive signals from a voltage source where: 4V = Inactive (0) Limit +35V This action is reversed if the input has been configured as ‘Inverted’ Digital Outputs (Relay, Thyristor or SSR Drive in any combination) External power supply 10 to 35 Vdc. Each output is current limited to 40mA Relay + _ Relay Outputs are open collector DC D1 D2 Relay Thyristor Unit SSR Thyristor Unit SSR D3 D4 D5 D6 D7 Figure 2-9: Wiring Connections for Digital I/O 2-10 Installation and Operation Handbook Part No HA026502 Issue 1.0 Apr-00
2704 Controller Installation 2.4. OPTIONAL PLUG IN MODULE CONNECTIONS 2.4.1. Digital Communications Connections Digital Communications modules can be fitted in two positions in the 2704 controller, (see also section 1.5). The connections being available on HA to HF and JA to JF depending on the position in which the module is fitted. The two positions could be used, for example, to communicate with ‘iTools’ configuration package on one position, and to a PC running a supervisory package on the second position. The connections shown in the following diagrams show RS232, 2-wire RS485, 4-wire RS422 and master/slave comms to a second controller. The diagrams show connections for ‘bench top test’ wiring. For a full description of the installation of a communications link, including line resistors, see Communications Handbook, Part No. HA026230, and EMC Installation Guide, part no. HA025464.
