1.1 Product Description
The PD/CTX TM is an intelligent current transmitter. It is used in
conjunction with a pulse density signalling, PDS(IO), logic output
from a series 2000 controller, to control a time proportioned Solid State
Relay (SSR) or Contactor. The two logic wires which operate the SSR
also carry load current and status information back to the controller.
This is referred to as ‘PDS Mode 2’ operation. Mode 2 provides:
1. Display of true RMS load current
2. High and low current alarm
3. SSR short circuit
4. Heater failure
An alternative capability, referred to as ‘PDS Mode 5’, allows the
PD/CTX to monitor relay or triac output controllers. The PD/CTX
uses the logic inputs of a series 2000 controller to transfer the data to
the controller. This version is used with external mechanical or
mercury contactors and line voltage SSRs. Mode 5 provides the same
features as mode 2 but it can also monitor the PD/CTX for open or
short circuit conditions and initiate an alarm in the controller.
The PD/CTX must be supplied for either mode 2 or mode 5 operation.
It is not field alterable. Before connecting the PD/CTX to the controller
check the product type against the order code given in section 1.9.
1.2 Compatible SSRs
The SSR must have AC output and DC logic drive input. The output
drive signal on the flying leads from the PD/CTX has a specification of
5-7Vdc at 7mA maximum. Most SSRs are typically rated at 3-32Vdc
but only those with input current requirements of less than 7mA are
suitable.

1.3 Load Current Signalling
The PD/CTX measures the AC current (45 to 65Hz) in the AC feed
wire passing through the unit. The RMS value of this current is sent to
the controller for display. The minimum resolvable current for a single
turn through the PD/CTX is 2A. Should you wish to read currents
lower than this it is necessary to increase the number of turns through
the PD/CTX. Please refer to the relevant controller manuals for further
details.
1.4 Mechanical Details
In Mode 2 operation, the PD/CTX is designed to be attached to a low
DC control voltage SSR mounted on a suitable heat sink. The bracket
on the PD/CTX is intended to be mounted underneath the SSR
mounting screw on the high current side of the SSR as indicated in
Figure 2. Do not fit the mounting bracket under the SSR itself.
Alternatively, the PD/CTX can be mounted to a flat plate, using the
attached bracket. This method of mounting is designed for use with an
external contactor or relay.
