Interface modules (accessories)

The Master and Command can be supplemented with further interface modules, which are simply inserted into two
module slots (see Section 3) at the back of the control head.
The following modules are currently available:
1. RS 232/485 Interface Module (Order No. LRZ 913) with 9-pole SUB-D socket. Electrically isolated
through optocouplers. Command set largely compatible with the ECO, Ecoline, Integral XT and Integral T Se-
ries. The RS 232 interface can be directly connected to the PC with a cable wired 1:1 straight through (Order
No. EKS 037).
Further details can be found in section 8.3.
2. Analog Module (Order No. LRZ 912) with two inputs and two outputs on 6-pole DIN socket. The inputs and
outputs can be set independently as 4 – 20 mA, 0 – 20 mA or 0 – 10 V interface.
Further details can be found in section 8.4.
3. Contact Module (Order No. LRZ 915) on 15-pole SUB-D socket. With three relay contact outputs (change-
over, max. 30 V/0.2 A) and three binary inputs for control via external voltage-free contacts. Plug 15-pole,
Order No. EQM 030 and plug case Order No. EQG 017.
Further details can be found in section 8.5.1.
4. Contact Module (Order No. LRZ 914) with connector to NAMUR NE28. Functionality as LRZ 915, but only
one output and one input on each of two DIN sockets. Coupling socket 3-pole, LAUDA Order No. EQD 047
and coupling plug 3-pole, LAUDA Order No. EQS 048.
Further details can be found in section 8.5.2.
5. Profibus Module (Order No. LRZ 917).
Further details can be found in the operating instructions Q4DA-E_13-014.
6. Pt100/LiBus Module (LAUDA catalogue no. LRZ 918)

Heater rating and power consumption from the mains

The Proline Low-Temperature Thermostats have an extraordinarily high heater rating of 3.5 kW maximum. If your
mains fuse is rated below 16 A, the current consumption can be reduced in steps from 16 A to 10 A ( 7.7.5). The
maximum heater rating of 3.5 kW is reduced accordingly.

For the connection of the Command remote control unit from the Proline
equipment line and other accessories, such as a solenoid valve for cooling
water control or a reverse-flow protection device.
