Pneumatic Timers
The BCH Pneumatic Timer (Time Delay Relay) is a proven, time-tested product built to deliver excellent timing accuracy even in adverse environmental conditions. Available in AC or DC supply with 30/60/180 second ranges and PN, PNI & PCN type logic, it is widely used in crane applications, starter panels and railway signalling. Supplied by Pankaj Enterprises as part of the genuine BCH range.
Product Description
BCH Pneumatic Timers, also known as Time Delay Relays, are engineered to deliver precise, dependable timing in demanding industrial environments. A completely enclosed timing head and encapsulated coil protect the mechanism against dust, moisture and corrosion, ensuring consistent performance even in adverse site conditions.
The range is available in PN type (On Delay), PNI type (On Delay + Instantaneous) and PCN type (On Delay + Off Delay), each offered with 1NO+1NC or 2NO+2NC contact blocks and AC or DC supply. Every part of the timer — coil, contact blocks and timing head — is independently replaceable, keeping maintenance simple. A dedicated railway-application variant with a fixed 120 sec or 150 sec on-delay is also available.
Applications
- Crane control and hoisting starter panels
- Railway signalling and coach maintenance applications
