What started decades ago with the development of a two-hand safety relay has continued and extended to form an extensive Dold safety relay module range over the last 15 years. From single function Dold safety modules to Dold modular multi-function safety systems with field bus connections, Dold safety devices are designed to protect both man and machine.
To assist machine and system manufacturers in designing safety-related circuits using discrete contactor hardware, Dold offers type-tested Dold safety devices allowing tailored solutions to be installed with respect to functionality and cost.
Dold Emergency Stop Relays
The function of a Dold emergency stop module is to quickly and reliably stop a dangerous movement when a potential hazard is identified.
Dold Safety Gate Monitoring Relays
Dold safety gate monitoring relays watch the position of movable safety devices by interrogation of safety switches which are operated by safety device opening/closing.
Dold Light Barrier Controllers
Dold light barriers belong to electro-sensitive protective equipment (ESPE) which cut off dangerous movements and initiate a safe condition when persons or objects approach to a dangerous location. Dold light barrier controller part numbers include:
- Dold LG5925/900
- Dold BG5925/900
- Dold BH5902/01MF2
Dold Two-hand Control Relays
Dold two-hand controls on machinery and plants are used to protect operators against injuries by dangerous closing movements. The control unit is located outside the dangerous area to prevent the operator from getting into this area before a dangerous movement is actually stopped. Dold two-handed control relay part numbers include:
- Dold BD5980N
- Dold BG5933
- Dold LG5933
- Dold BH5933
Dold Safety Mat Relays
These Dold safeguard products generate a control command when exposed to an operating force and cause an immediate stop of a dangerous movement via an evaluator module. Dold safety mat relay part numbers include:
- Dold BG5925/910
Dold Extension Relays
Dold extension relays can be used to multiply the output contacts of the basis modules. Also they can be used as contact reinforcement by splitting into multiple control circuits is possible.
Dold Standstill / Speed Monitoring Relays
Dold stand-still / speed relays monitor the rotation of drives to generate a control signal at zero speed or when a set speed is exceeded. Dold speed relay part numbers include:
- Dold BH5932
- Dold UH5947
- Dold LH5946
Dold Multifunction Safety Solutions
In the compact Dold multifunctional SAFEMASTER safety module several safety-related inputs are assigned to a single output. With Dold SAFEMASTER it is possible to tailor the safety functions to the relevant application in a cost-saving manner.
Dold Wireless Safety
Dold SAFEMASTER-W, a wireless companion for your safety, allows for remote access to dangerous areas of machinery to carry out machine settings or fault elimination. Also Dold wireless solutions allow you to cut off dangerous movements within a fraction of a second.
