Safety module UH 6940
Multifunctional stand-alone safety module

With the new programmable stand-alone module SAFEMASTER PRO COMPACT Dold is expanding its safe automation product portfolio for controlling smaller machines and plants. With a width of only 45 mm, the compact safety module UH 6940 offers you 16 safe inputs and 4 pairs of OSSD outputs. The UH 6940 monitors numerous safety functions such as emergency stop, safety mats, safety light curtains, safety switches etc. in just one device. This saves costs and space in the switch cabinet.

For safety applications up to Cat. 4 / PL e or SIL 3
Easy engineering via drag & drop with software
Programming and diagnostics via USB
Simple combination with SAFEMASTER STS

Extension module RK 6929
Safe contact extension with only 17.5 mm

The extension module RK 6929 from the SAFEMASTER series offers up to two separately controllable forcibly guided relays in a compact enclosure with a width of only 17.5 mm and is used to decouple the control and power levels as well as for contact reinforcement. As an output extension for signals from safety control systems (OSSD), the RK 6929 switches actuators reliably and potential-free. The extension module can be used in mechanical and plant engineering as well as in applications for firing systems in accordance with EN 50156-1. For use in the application area of EN 61010-1, the clearances and creepage distances between mains circuits and touchable voltages as well as between mains circuits are dimensioned according to double insulation.

Space-saving in the switch cabinet due to a width of only 17.5 mm
Control also with safety-related semiconductor outputs
Interface type C class 1 (CB24I)

Coupling device RR 5898
Insulation monitoring for IT systems up to DC 1500 V

The combination of the insulation monitor RN 5897/010 and the new coupling device RR 5898 is predestined for use in modern applications in which the insulation of IT systems with high voltages needs to be monitored. The devices from the VARIMETER IMD series are suitable for the reliable monitoring of power supplies such as battery energy storage systems (BESS), but also for applications such as test and inspection systems. By detecting insulation faults in unearthed systems at an early stage, the insulation monitor RN 5897/010 ensures increased operational and system safety.

For nominal voltages up to AC 1000 V and DC 1500 V
Can be used in unearthed AC, DC and AC/DC systems
Also suitable for Modbus variant RN 5897/011

Insulation monitor RN 5893
IMD with UL 2231 approval - especially for DC charging stations

Electrical safety must be guaranteed during the charging process. For this purpose, an unearthed DC power supply system (IT system) with insulation monitoring is set up and monitored with an insulation monitoring device (IMD). Dold has developed a smart insulation monitoring solution for DC charging stations that also fulfils the requirements of UL 2231. The insulation monitor RN 5893 from the VARIMETER IMD family monitors the charging process from the charging station to the vehicle in combination with the coupling device RP 5898.

Response delay < 10 s
Nominal voltage up to DC 1000 V
Manipulation protection due to sealable transparent cover

Sensorless standstill monitor UG 9146
Sensorless standstill monitoring

The sensorless standstill monitor UG 9146 from the VARIMETER series is used for sensorless monitoring of electric motors for standstill. This means sensors such as encoders or proximity switches are not required. The standstill monitor measures the induced voltage of the coasting motor. If the induced voltage approaches 0, this means motor standstill for the device and the output relay is activated. With a width of only 22.5 mm, the UG 9146 can be installed in switch cabinets with limited space as well as in retrofit applications.
