Unlike other alternatives on the market, Hongfa’s HF115FP interface relay from Switchtec has a lockable test button, mechanical flag indicator and a LED that are all supplied as standard. These features are common across Hongfa’s whole range of interface relays.
Aimed at panel builders, system integrators and process control applications, the HF115FP is available in single and double pole versions, rated at 16A and 8A consecutively. Showing versatility, the HF115FP is available in 12, 24, 48 and 110VDC, and in 24, 110 and 230VAC coil versions. The relay’s lockable test button is colour coded for quick and easy voltage recognition; blue for DC and orange for AC.
The HF115FP’s mechanical test button is a great aid during commissioning, fault tracing and when override situations are needed.
The HF115FP has evolved from, and utilises the technology deployed in the popular HF115F Series. This gives the HF115FP a compact design with the bonus of the additional features. It also has a clear (tinted) case, making the relay’s contacts clearly visible. The relay’s LED is a dual (Bi-directional) type.
The HF115FP uses PCB pins for its electrical connections. This enables the relay to be mounted directly on to a PCB (without the need for a PCB socket) or, via its industry standard footprint it can be plugged into Hongfa’s 14FF-2Z-C3 DIN socket. The 14FF socket features an ejector style retaining and release clip for easy removal of the relay. ID tag and further indication or EMC suppression can easily be added using HF plug in modules.
The HF115FP can be supplied alone for PCB or plug in mounting, or it can be supplied pre-assembled into the 14FF socket as part of the popular RM relay interface modules range. For use all around the globe, the HF115FP carries joint CUL approval, VDE and CE.
Together with the whole range of Hongfa relays, the HF115FP is available ex stock on quick delivery times from Switchtec.
Evolution
Hongfa’s HF115FP is an evolutionary development of the standard miniature interface relay. Historically this product comprised a relay plugged into a socket with an LED module, and traditionally the larger 8, 11 and 14 pin relays are supplied with lockable test button, flag indicator and LED as standard. The facility to add a lockable test button, flag indicator and LED to the miniature relay was recognised as an application solution by Hongfa. As mentioned, the mechanical test button is useful during commissioning, fault tracing and when override situations are needed. The built in LED removed the need for additional LED modules and the flag indicator is a mechanical indicator, showing the position of the contacts even when there is no supply the to relay.
