Use of the TELEFAST Wiring Accessories

At a Glance

The TELEFAST pre-wired system consists of connecting cables and interface sub-bases as shown below:

Shield bar

Clamp

The TELEFAST ABE-7CPA410 accessory is a base unit used for the connection of sensors. It has the following functions:

Extend the input terminals in voltage mode.
Supply, channel by channel, the 0-20 mA or 4-20 mA sensors with a protected 24 V voltage, limited in current to 25 mA, while maintaining isolation between the channels.
Protect current reading resistors that are integrated in TELEFAST against overvoltage.

Channels to channels isolation	750 Vdc
Channels to 24Vdc supply isolation	750 Vdc
Overvoltage protection on current inputs	By Zener diodes 8,2V

NOTE: When using current inputs, the TELEFAST 250 Ohm resistors are used, as opposed to those of the module. The BMX AMI 0410 module operates in voltage mode.

BMX FCA ••0 Connecting Cables

The BMX FCA ••0 cables are pre-assembled cord set, made up of:

At one end, a compound-filled 20-pin terminal block from which extend 1 cable sheath containing 20 wires,
At the other end a 25-pin Sub-D connector.

The figure below shows the BMX FCA ••0 cables:

Length according to the part number.

The cable comes in 3 different lengths:

1.5 m (4.92 ft): BMX FCA 150
3 m (9.84 ft): BMX FCA 300
5 m (16.40 ft): BMX FCA 500

The following table gives the characteristics of the BMX FCA ••0 cables:

Characteristic		Value
Cable	Sheath material	PVC
Cable	LSZH status	No
Environmental	Operating temperature	-25...70 °C (-13...158 °F)

Connecting Sensors

Sensors may be connected to the ABE-7CPA410 accessory as shown in the illustration.

The following table shows the ABE7-CPA410 and SUBD25 terminal numbers:
