Product catalog summary
Overview: The 385A Series is a panel-mounted digital timer and counter designed for versatile timing and counting applications. It features programmable modes, multiple relay actions, and a compact design.
Specifications: The timer mode covers a span from 0.01 seconds to 999 hours across nine ranges, while the counter mode spans 1 to 99,900 counts in two ranges. It includes dual DPDT relays rated at 7A for 120 or 240 VAC.
Features: The device offers multiple starting options, including momentary or sustained start signals, and can operate with or without voltage. It includes new flip-flop timer/counter modes with batch and dwell functionalities. The LED dual display shows cycle progress and preset selections.
Memory and Computation: The 385A retains its program and preset periods even during power loss, thanks to non-volatile memory. It can recompute time/count-out instantly if the set point changes during a cycle.
Design and Setup: Housed in a 72mm2 DIN casing, the 385A is compact and dust-tight. Setup is facilitated by 16 DIP switches, eliminating complex programming codes. The unit is a plug-in design for easy replacement.
Operation Modes: The 385A supports four modes of operation, including standard timer/counter and flip-flop modes. It can function as an ON-Delay or OFF-Delay timer/counter and supports both single and repeat cycles.
Display and Presets: The dual display shows timing progress and preset values. There are three programmable presets and a totalizer for each mode. Preset 3 can be set as a count or time input.
Wiring and Terminals: The device requires power to specific terminals and can start timing or counting with voltage applied to the clock/count input terminal. The start/reset terminal can be configured for voltage or no voltage start.

800.727.5646 automatictiming.com Automatic Timing & Controls 385A Series Panel Mounted Digital Timers// 385A Series 109 In the timer mode, the 385 can be programmed to cover the overall span of 0.01 SEC to 999 HR in nine ranges, and can be programmed to time in Hours:Minutes and Minutes:Seconds. In the counter mode, it can cover the overall span of 1 to 99,900 counts in two ranges. MULTIPLE RELAY ACTIONS: The relationship between the 385’s two DPDT relays, Relay 1 and Relay 2 can be programmed for any of the four modes of operation to satisfy virtually any control scheme. MULTIPLE STARTING OPTIONS: The 385 can be easily programmed to start with a momentary or sustained start signal. The start signal can also be set for a voltage or no voltage starting condition. NEW TIMING AND COUNTING MODES: The 385 has two new modes of operation. The flip-flop timer/counter with batch, which can be programmed to function as a flip-flop that will stop after a certain number of cycles or a time span. The other new flip-flop function is a standard flip-flop with a programmable dwell between the relays. DISPLAY: The display is an LED dual display which can be programmed to run UP to or DOWN from the set point. The lower display shows the preset selected to view and the upper display shows the cycle progress. NON-VOLATILE MEMORY: The 385 retains its entire program and preset time/count periods even when there is a loss of power. No batteries are required. REAL-TIME COMPUTATIONS: The 385’s microcomputer instantly recomputes time/count-out when there is a change in the set point during a cycle. This allows you to shorten a cycle without loss of accuracy. COMPACT, PLUG-IN AND DUST-TIGHT: Packaged in a 72mm2 DIN housing, the 385 takes 40% less panel space than conventional timers. A true plug-in design, it can be replaced in seconds without disturbing housing or wiring. Fully gasketed and sealed, it is dust tight in panel mounted installations. SETUP: Setup of the 385 is accomplished using 16 DIP switches which are located inside the unit. These DIP switches give a visual indication of how the Controller is setup, and eliminates the use of complex programming codes.

800.727.5646 automatictiming.com Automatic Timing & Controls 385A Series Panel Mounted Digital Timers // 385A Series 111 THE DISPLAY: A highly visible dual display consists of three digits with a movable decimal point or four digits for counting. There is a horizontal timing bar “ ” which appears to the right of the upper display and blinks once per second during timing. This is very useful in showing that the timer is timing especially when the digits do not change rapidly as in the hours ranges. The timing bar blinks rapidly at time-out as well. The lower display is DIP switch selectable to...
