A.
PRESENTATION
The STB 320 terminal block enables 32 relay-type isolated digital outputs to be
implemented under the control of an output board located in a system.
The module can receive :
= Electromechanical relays
= Solid-state relays
The design of this product is geared to industrial process control where safety and
dependability criteria are essential.

OPERATION
B.1.
RELAY OUTPUTS
The STB 320 terminal block has 32 relay outputs.
For each channel, the following three contacts are available :
= normally open,
= normally closed,
= common.
Provided that the relay chosen allows this.
The breaking capacity depends on the relay chosen in the characteristics sheet.
The following products are "supported" by the STB 320 terminal block :
= VERSION RB : TK 1-4-5 or TQ2-3
NAIS / SDS
= VERSION RH : DSP 1-5
NAIS / SDS
= VERSION SB : HSSR 8060
HEWLETT PACKARD
= VERSION SH : HSSR 8400
HEWLETT PACKARD
N.B. : See documents which follow.

B.2.
"SAFETIES" MODE
The STB 320 terminal block has two inputs galvanically isolated by photocouplers which
can be used by safety loops.
= GROUP 1 safety for channels 0 to 15.
= GROUP 2 safety for channels 16 to 31.
The photocouplers used are HCPL 3700 particularly well-suited to industrial
environments.
The "safety" signals can be AC or DC.
The resistances R1 and R2, mounted on studs, are adjusted according to the sensitivity
of the input chosen.
The capacitors C1 and C3 performs filtering of said inputs.
The table below describes the values chosen according to the levels :

The STB 320 terminal blocks are delivered for "safety" signals of 24V.
SAFETY MODE :
B.3.
GR1 = ST100 = AB
GR2 = ST200 = AB
"AUTONOMOUS" MODE
In this operating mode, the "safety" inputs are not taken into account :
GR1 = ST100 on BC
GR2 = ST200 on BC
B.4.
VOLTAGE EMISSION
The STB 320 terminal block has two "commons", one for each group. This feature does
away with a large amount of wiring in certain applications.
Straps from ST0 to ST31 enable this possibility to be implemented or not.

USE
C.1.
CONNECTION TO PROCESS
Connection to the process is performed by plug-in terminals.
The diameter of the wire must be smaller than or equal to 1.5mm2.

LOGIC SUPPLY
The STB 320 terminal block requires a + 5V logic supply.
This can be provided :
- either by the two terminals provided for this purpose (which is preferable),
- or by the coupler board via pin 50 of J2, if the length does not exceed 1.5m between
the board and terminal block.
C.3.

Leds show the status of the relays.

CONNECTORS - J1/J2
The output signals from the STB 320 are available on two connectors :
J1 (HE 10/34 pins) and J2 (HE 10/50 pins). The following listings illustrate the pin
assignments.
