3.4.4Relay Output, Contact Input

WARNING

To prevent the possibility of electrical shock, use extreme caution when wiring contact output connections. Hazardous potentials may exist on contact output terminals which are floating with respect to instrument ground. These hazardous potentials may be exposed on the rear terminal panel of your instrument. Any voltage potentials at the contact circuit will exist on the instrument’s respective contact output terminals (i.e. line-powered circuits).

The Recorder may be equipped with an optional Digital Input Output Board which has A combination of up to 12 potential free Form A (Single Pole Normally Open) or Form C (Single Pole Double Throw) relay contacts and up to 6 opto-isolated digital inputs. The combination depends on the option chosen. An example is shown below.

Figure 3-11 Digital I/O Module 12 Contacts Out, 2 In

This module has 12 Potential Free Form A Normally Open (NO) connections. Connection is two wire and there is no polarity. Maximum switching voltage is 200 Vdc and 0.5 Amp at a Maximum of 10 Watts (Voltage x Current <10W) per contact. The potential free relay contacts are protected internally with 270 volt Metal Oxide Varistors (MOVs) to prevent contact arcing.

There are two optically isolated digital inputs which accept 12 to 24 volt DC inputs (These can be jumpered internally on the circuit board for 5 to 12 volt DC operation – see Appendix B). The inputs are polarity aware and are marked plus (+) and minus (-) accordingly. Check the specification of the specific module in your unit for full specifications.

3.5 Ethernet

The 10BaseT Ethernet option allows direct connection to the LAN or WAN and the standard TCP/IP protocol enables the transfer of data over the Internet. The RJ45 Connection for the Ethernet is as follows:

Receive Differential Pair

Transmit Differential Pair

3 RX-

7 TX-

6 RX+

8 TX+

Two LEDs on the rear panel show Ethernet activity. The Amber Link Speed LED indicates
