Model 385AR 1/16 DIN Timer Counter

The Model 385AR 1/16 DIN Timer Counter from the Automatic Timing and Controls division of Marsh Bellofram Corporation is an accurate, cost-effective, 10-in-1 multi-function multi-range industrial timer/counter, offering the benefits of 10 unique operating modes within a single unit. It is designed to accept standard voltage inputs of 3 to 30V DC, making it compatible with most industry proximity switches, solid state devices, as well as potential free contact encoders. Three unique input speeds, of 3 Hz, 30 Hz, and 5 kHz, respectively, are also standard. The series further incorporates a built-in 12 VDC 30 mA sensor power supply with integral short circuit protection, as well as options for front panel or remote reset. The 385AR series will also reset on power interruption. The timer/counter mechanism of the Model 385AR is packaged within a highly compact 1/16 DIN (48 x 48 mm) housing with 2 SPST (NO) 5a @ 230 VAC contacts. Standard operating voltage range supply is 85 to 270 VAC/DC (50/60 Hz), with a maximum power consumption rating of 5VA.

In addition, series units feature a large, easy-to-read, four-digit, seven-segment LED display. They also incorporate dual setpoints, programmable input scaling, and batch counting, with a standard time setting accuracy of 0.05%, and onboard memory retention. A special onboard LED status indicator offers a unique and effective method for visual control indication. Units are also both UL recognized and CE certified. They are easy and quick to both install and maintain.

The unique versatility and accuracy of the Model 385AR 1/16 DIN Timer Counter make it well-suited for applications such as OEM equipment, packaging and plastics manufacturing, machinery monitoring and control, materials handling, conveyor control, motors, compressors and pumps, and industrial process control. It is also particularly useful within cost-conscious manufacturing environments, in which the benefits of its multi-functionality and relatively low cost make it an invaluable component of any streamlined in-house maintenance strategy. Here, the Model 385AR can be an effective drop-in replacement for multiple industry 1/16 DIN industrial timer and counters, thereby reducing in-house inventory costs via the specification of a single and highly effective model to meet more universal application requirements.

All Marsh Bellofram quality products are available from the company’s global corporate headquarters in Newell, West Virginia, with typical standard lead times of less than 10 business days.  Expedited deliveries are available upon request.
