The miniature pneumatic timer is an adjustable timing device that offers excellent repeat timing and setting accuracy, typically used as an ON delay or an OFF delay function to signal other valves or devices within purely pneumatic systems. Setting the pneumatic timer is achieved by adjusting the front rotary knob to the desired set point; there are two vertical scales; one indicates the setting time and the other the time remaining in the cycle. 5 million cycles 30 m/s (10-500 Hz) 400 m/s (during 5 ms) IP40 when connected. IP55 when using a polycarbonate transparent cover. 0°C to +60°C Medium temperature: Maximum 30°C (compressed air temperature). Display: Housing: • ON delay timers.
The timing sequence begins by applying compressed air to port 1. On reaching a preset value, port 2 connects to port 1. The output at port 2 remains on whilst air to port 1 is connected. Air removal from port 1 resets the preset timing value, and the output from port 2 disconnects from port 1. • OFF delay timers. Port 2 to 1 is connected. The timing sequence begins by applying compressed air to port 12. On reaching a preset value, port 2 closes. The output at port 2 remains closed whilst air to port 12 is connected. Air removal from port 12 resets the preset timing value, and port 2 to 1 reconnects. Digit roll Plastic material.
Product S election Mini timers can be built into the front panel of equipment. Panel cut-out: 45mm (+0.6) x 22.2mm (+0.3) and secured in place with a fixing clip. Please ensure the panel cut-out is large enough that the timer is not placed under mechanical tension or strain when built in. Additionally, a panel frame, part number 1499512, provides a wider aperture giving a professional looking finish to panels. Panel frames are used individually or with protective covers. Din-rail mountings allow the timer to be mounted inside a panel for additional protection and also to prevent tampering. Installation & Mounting Pneumatic Connections Mini timers are provided with threaded M5 connections.
Please ensure a tight seal is provided by fully inserting tubing and by tightening threads sufficiently providing a proper seal. We recommend the use of self-sealing fittings, this is a fitting that incorporates an NBR sealing ring. We do not recommend the use of thread sealing compounds. Due to the close proximity of ports we recommend a cylindrical shape fitting. Accessories 50010N-04-05 M5 to 4mm o/d tube 50010N-06-05 M5 to 6mm o/d tube Timing Reset Automatic reset by air removal. ON delay timers by removal of air to port 1. OFF delay timers by removal of air to port 12. ATEX Not suitable for external or harsh environments. Protect from corrosion.
General advice is to house within an enclosure or control panel with suitable protection rating or use a protective cover. See accessories. Environment As well as standard timing devices which are intrinsically safe, we offer ATEX fully certified, CE-marked pneumatic timing products that comply with the ATEX directives for use within category M2 and group II, zones 1 and 21. See product selection. ATEX timing products (57.020.03.EX, 57.020.30.EX, 57.020.33.EX, 57.020.34.EX, 57.021.03.EX, 57.021.30.EX) conform to the following standards: Air Quality Clean, dry and oil free air to instrument quality standards.
Please note that at low operating/ambient temperatures air filters alone will not be sufficient. Air dryers are recommended to achieve low moisture dew point. Exhaust Compressed air will exhaust from this device as part of the operating sequence. This could be sufficient volume and pressure to create risk or introduce problems within an enclosure. Our declaration of conformity can be downloaded from https://www.impulseautomation.co.uk/downloads Safety & Warnings Warning: ATEX products should never be used in Zone 0 or Zone 20, as defined in IEC 60079-10-1:2015 and IEC 60079-10-2:2015.
Only competent qualified persons should install, mount, attach hoses, initially operate, maintain, test and disassemble this product. Never disconnect power lines or service the device when the system is powered. This product should only be used for its intended purpose and within the limits and conditions as described. When cleaning or servicing the product, to avoid electrostatic discharges, use a damp anti-static cloth. The system builder is responsible for ensuring that the final system meets any hazardous zone, EX or ATEX requirements.
